Description
Technical field
The present invention relates to epoxy resin adhesive technical field, the modified epoxy adhesive of particularly a kind of high intensity
And preparation method thereof.
Background technology
The metal through strict surface treatment for the current high-performance modified epoxy resin adhesive bonding and nonmetallic all have
Good adhesive strength and endurance quality, but bonding is without the strict metal being surface-treated and nonmetallic, not only adhesive strength
Low, and endurance quality is poor.Such as conventional high-performance epoxy resin adhesive modification e51 epoxy resin is matrix resin,
The adhesive of 200# polyamide curing agent preparation, has good bonding intensity and endurance quality, and bonding phosphoric acid is processed
Ly2cz aluminum alloy surface, normal temperature shear strength can reach 37mpa, 55 degree of rh98-100% hydrothermal agings 1000 hours and 90 degree
The adhesive property that shear strength after aging 300 hours for the salt fog is compared under normal temperature also increases, excellent in durability, but bonding
The aluminium alloy that sand papering is processed, even without the section of the sheet material being deliberately surface-treated, normal temperature shear strength only has
19.23mpa, the 55 degree of rh98-100% hydrothermal agings 1000 hours and 90 degree of salt fogs shear strength after aging 300 hours is almost
Zero.Domestic temporarily still do not have a kind of adhesive good for having without the strict metal being surface-treated or nonmetallic surface or section
Good adhesive strength and endurance quality.
Content of the invention
It is an object of the invention to provide modified epoxy adhesive of a kind of high intensity and preparation method thereof.
The technical solution realizing the object of the invention is: a kind of modified epoxy adhesive of high intensity and its preparation
Method, described modified epoxy adhesive press mass fraction by 80～100 parts epoxy resin, 3～21 parts of carboxyl butyronitrile glue
Breast, 1.1～7.7 parts of polyacrylic ester latexs, 5～10 parts of silica flour, 1.1～1.5 parts of alumina silicate, 2-3 part anti-settling agent, 1～3 part

(b) by after polyacrylic ester latex breakdown of emulsion, dry for standby；
C () carboxylic acrylonitrile butadiene rubber latex after step (a) is added in epoxy resin, react 2h under conditions of temperature is 120 DEG C,
Sequentially add the polyacrylic ester latex after step (b) and gamma-aminopropyl-triethoxy-silane, the condition being 120 DEG C in temperature
Lower reaction 1h, obtaining is the epoxy resin of thick liquid under normal temperature；
D () sequentially adds anti-settling agent, alumina silicate and silica flour in the epoxy resin of thick liquid, after stirring 40min, obtain final product height
The modified epoxy adhesive of intensity.
The present invention compared with prior art, its remarkable advantage: the present invention have resistance to ablation, anti-soda acid, moisture absorption heat endurance,
Ageing-resistant, anti-shearing force, height insulate, the excellent properties of high sealing, can be effectively ensured in the metal without strict surface treatment
Or nonmetallic surface or section have good bonding intensity and endurance quality, in terms of electrical insulation properties, add due in formula
